For making any 'ANDROID APP' what r some various terms one must know, will be provided through this small PRESENTATION.

1. • Android is an open-source software platform
created by Google and the Open Handset
Alliance.
• It is primarily used to power mobile phones.
• It has the capability to make inroads in many
other (non-phone) embedded application
markets.

2.  • Android is a software environment built for mobile
 devices.
 • It is not a hardware platform.
 • Android includes:
 • Linux kernel-based OS,
 • a rich UI,
 • telephone functionality,
 • end-user applications,
 • code libraries,
 • application frameworks,
 • multimedia support, ...
 • User applications are built for Android in Java

4.  Application framework enabling reuse and replacement of
components
 • Dalvik virtual machine optimized for mobile devices
 • Integrated browser based on the open source Web Kit engine
 • Optimized graphics powered by a custom 2D graphics library; 3D
graphics
 based on the OpenGL ES specification (hardware acceleration
optional)
 • SQLite for structured data storage
 • Media support for common audio, video, and still image formats
(MPEG4,
 H.264, MP3, AAC, AMR, JPG, PNG, GIF)
 • GSM Telephony (hardware dependent)
 • Bluetooth, EDGE, 3G, and WiFi (hardware dependent)
 • Camera, GPS, compass, and accelerometer (hardware
dependent)
 • Rich development environment including a device emulator, tools
for
 debugging, memory and performance profiling, and a plugin for the
 Eclipse IDE

5.  • User applications, as well as core Android
 applications, are written in Java programming
 language and are compiled into byte codes.
 • Android byte codes are interpreted at
runtime
 by a processor known as the Dalvik virtual
 machine.

7.  An Intent in Android describes what you
want to do because they facilitate
navigation and represent the most
important aspect of Android coding.
 • An Intent Filter is a trigger, a
declaration of capability and interest in
offering assistance to those in need.
 • An Intent Filter may be generic or
specific with respect to
which Intents it offers to service.

8.  • Every application must have an
AndroidManifest.xml file (with precisely that
name) in its root directory.
• The manifest presents essential information
about the application to the Android system,
information the system must have before it can
run any of the application's code
e.g.- action, permission, action etc.
